A starship is traveling toward earth at a speed of 0.85c when it experiences a major malfunction and the crew is forced to evacuate. An escape pod that is 10.5 m long with respect to its passengers is ejected from the starship and sent toward earth at a speed of 0.76c with respect to the starship. How long does the escape pod appear to the people on Earth?

c. Remember that a light-year is defined as the distance, relative to Earth, that light travels in one calendar year on Earth. If Alpha Centauri is 4.37 light-years away from Earth, what is this distance measured by you from your spaceship? d. You and your twin decided to synchronize your clocks before you started your trip so you can compare the length of your trip once you get back. i. How long does it take the spaceship to reach its...
Light requires 4.5 years to travel from the nearest star to earth
Light requires 4.5 years to travel from the nearest star to earth. If we could travel there in a spaceship going 90% of the speed of light, the trip would require 5.0 years according to clocks on earth. How much time would pass for the passengers in the ship?

ANSWER 3A, B, AND C!
3. The star system that is closest to the earth is Alpha Centauri. It is 4.37 light years away in Earth's reference frame. The fastest spacecraft humans have ever launched is New Horizons, which sent us sweet pictures of Pluto in 2015. It attained a speed of 45 km/s relative to the sun. That's fast, but even at this rate, interstellar travel is not practical. a) Traveling at 45 km/s, how long, in years, would...

3. Your starship passes Earth with a relative speed of 0.9990c. After traveling 10.0 y (your time), you stop at lookout post LP13, turn, and then travel back to Earth with the same relative speed. The trip back takes another 10.0 y (your time). How long does the round trip take according to measurements made on Earth? (Neglect any effects due to the accelerations involved with stopping, turning, and getting back up to speed.)
